We know that Simone is going to snowboard tomorrow if the temperature is equal to or colder than 5 degrees Celsius. Equal to or colder basically means less than or equal to. The sign for that is ≤. Since we know that t is less than or equal to 5 degrees Celsius, we can substitute the ≤ sign for less than or equal to, giving us our inequality of t ≤ 5.

ANSWER:
f(x)⁻¹ = (x+10)/2
WORKING OUT:
f(x) = 2x - 10
y = 2x - 10
*Replace all 'y' values with 'x' and vice versa*
x = 2y - 10
*Make y the subject of the equation*
2y = x+10
y = (x+10)/2

$75
Step-by-step explanation:
Remove $25 from $150. (125)
Calculate 40% of 125. (50)
Remove that 40%. (75)
